The city’s upgraded 911 system appears to be hung up on a technical glitch.

According to The New York Post, the $195 million Vesta call processing program can’t handle tests simulating intense New York City Police Department and EMS call volume.

Officials are reportedly refusing to let the system go live in June when dispatchers finally move into a centralized emergency center.

The Post says the program, supplied by a Verizon subcontractor, crashed during a test that pumped 3,000 calls an hour into its phone lines for six days.

The paper reports the system is set to undergo another test of 6,000 calls an hour next month.

Since last October, the city has fed 20 million test calls into Vesta without problems.

Vesta is part of an extensive upgrade of the 911 call system by the Bloomberg administration.

The project is more than a year behind schedule and over budget.
